Abstract
Abstract A spray can for resin paints under pressure incorporates a secondary container in its interior for holding a catalyst. A spray means including a spray valve is received on one end of the cam and includes an elongated tube extending into the can. The secondary container includes inertia means in the form of a weight. The arrangement is such that shaking of the can causes the weight to shatter the secondary container thereby placing the catalyst and resin in communication with each other. Mixing of the ingredients can thus take place just prior to a spraying operation, the mixture passing up through the tube and out the spray means when the spray valve is opened.

A portable spray means for dual liquids comprising, in combination: an elongated cylindrical can; an elongated cylindrical secondary container of frangible material positioned in the interior of said can with its longitudinal axis running substantially longitudinally in said can; a weight in said secondary container of mass such that one end of said container can be shattered upon impact by said weight; spray means on said can including an elongated tube passing into said can and extending downwardly therein, said secondary container including a catalyst and said can containing a resinous liquid and gas propellant to be mixed with said catalyst, whereby shaking of said can back and forth generally in the longitudinal direction of the can causes said weight to shatter said secondary container and place said catalyst into communication with said resinous liquid and gas propellant; and a screen at the inner end of said elongated tube for blocking any fragments of said secondary container from passing up through said tube during a spray operation.
